    With over 12 years of experience, I specialize in crafting enterprise-level mobile and web applications using React Native, Flutter, and advanced JavaScript frameworks. My journey began with native app development, evolving into a hybrid app specialist with a deep understanding of both front-end and back-end technologies. This unique blend allows me to deliver secure, scalable, and high-performance solutions that are tailored to meet the unique needs of each client. Consult, Plan, and Deliver: I approach every project as a technical partner, not just a developer. My focus is on understanding the core objectives and aligning the technology and development process with your business goals. I guide clients through three crucial questions: Which services best fit your project? - Backend Development: With expertise in Node.js, I build robust backends using Nest.js, Express, and TypeScript, ensuring a strong foundation for your applications. - API Development: I design and integrate powerful APIs that seamlessly connect various services and microservices within a scalable architecture. - Mobile App Development: Mastery in React Native and Flutter, combined with native coding skills, allows me to create dynamic, high-performance mobile apps that are both user-friendly and robust. - Web Development: Leveraging React and Next.js, I create dynamic web applications that are responsive, secure, and scalable, ensuring a seamless user experience. Which technology aligns with your current and future goals? - Mobile: React Native, Flutter, Swift, Kotlin—delivering versatile mobile solutions with a focus on performance and user experience. - Web: React, Next.js, Node.js (Nest.js, Express)—building scalable web applications that integrate seamlessly with your backend services. - Infrastructure: AWS (Docker, Kubernetes, EC2, Fargate, VPC)—expertise in cloud infrastructure ensures your applications are scalable, secure, and cost-effective. - Third-Party Integrations: Sockets, Streaming, Polling, and various AWS services—integrating cutting-edge technologies and third-party services to enhance functionality and performance. What is the optimal development process for your project? - Wireframing & Prototyping: Early-stage visualizations to ensure alignment with your vision and goals. - Architecture Planning & Design: Whether monolithic or microservices architecture, I design scalable systems tailored to your project’s requirements. - Version Control & Collaboration: Utilizing Git and Gitflow to manage codebase effectively, ensuring a smooth and collaborative development process. - CI/CD & Automation: Setting up continuous integration and deployment pipelines with automated testing, ensuring efficient, error-free deployments. - Testing: Implementing comprehensive testing strategies, including automated testing, manual testing, and penetration testing, to ensure a secure, reliable product. Enterprise Success Stories: Throughout my career, I’ve successfully delivered high-impact solutions for major enterprises and government agencies. Notably, I’ve developed secure, reliable, and high-performance applications for the transportation and medical sectors in Ireland, aligning technical solutions with business goals to deliver products that are both scalable and future-proof. My work consistently meets and exceeds client expectations, driving business success through technology. Client Communication & Availability: One of my greatest strengths is my ability to communicate complex technical concepts in a clear, understandable way. I prioritize understanding your needs and providing well-considered solutions. Fluent in English, I ensure that communication is seamless across all platforms. I’m also committed to being available across various time zones, offering extended working hours to accommodate clients from around the globe. Commitment to Quality: My commitment to quality extends beyond coding. I believe in building long-term relationships with my clients, offering ongoing support and consultation even after project completion. My approach is proactive, anticipating challenges before they arise and addressing them with well-thought-out strategies. This ensures that every product I deliver is not just functional but also optimized for success in the competitive digital landscape.
